It should be in the kex_input_ext_info.


debug1: kex_input_ext_info: server-sig-algs=<rsa-sha2-256,rsa-sha2-512>

Additionally, sign_and_send_pubkey will typically indicate one of these two formats if they are being used:


debug3: sign_and_send_pubkey: signing using rsa-sha2-512 ...

Reading the logs you shared, it seems like the server does not support rsa-sha2.

Edit: Looking into this further, it's unclear if Azure DevOps supports rsa-sha2. rsa-sha1 is considered weak and not enabled by default in most clients. I'll continue to investigate.
